Hi AP People! Happy New Year!

We've got one week left of vacation. Here's a little AP homework for you to get re-acquainted with Java.

Do ONE javabat from each of the following sections:
Each javabat is worth 2 points.

http://codingbat.com/java/String-1
http://codingbat.com/java/Array-1
http://codingbat.com/java/Logic-1
http://codingbat.com/java/Array-2
http://codingbat.com/java/AP-1

Remember to login so that you get credit!

We are going back to objects and classes, a section we skipped in Chapter 4. (Also in Ch. 5)
Read pages 196 to 218.
Copy and answer the following questions:
Each question is worth 2 points. (One point for an answer, two points for correct answer)

Warmup-1 and Warmup-2
Try to finish this section, do as much as you can without looking at the answers

Remember that to loop through an array

(assuming your array is named list)

you would use the following for loop to loop from the first to last element:

for(int i = 0; i < list.length; i++)

{

// statements go here

Using the following array declaration

int[] list = new int[10];

Assign a random number between 1 and 100 to each array element. (Use Math.random())
Loop through the array and print every value.
Loop through the array and find the sum of all the elements.
Print the sum.
Calculate the average by dividing the sum by the length of the array.
Print the average.
Loop through the array and count the number of even numbers.
Calculate the number of odd numbers (10 - the number of even numbers).
Print the number of even numbers and the number of odd numbers.
FORMAT ALL OF THE PRINT STATEMENTS SO THAT THEY ARE DESCRIPTIVE
EXAMPLE:
The output for the average should look as follows:
